Answer:
x + y = 10
Step-by-step explanation:
The mean is calculated as
mean = 
, thus
= 5 ( multiply both sides by 6 )
20 + x + y = 30 ( subtract 20 from both sides )
x + y = 10
Answer:
a
Step-by-step explanation:
Find the area of the base and multiply it by the height
It would be the last answer, you can't simplify
Answer:
Step-by-step explanation:
These two angles are interior and on the same side of the transversal. Therefore they are supplementary.
6x + x + 5 = 180
7x + 5 = 180 Subtract 5 from both sides
7x = 180 - 5
7x = 175 Divide by 7
x = 175/7
x = 25
x + 5 = 25 + 5 = 30
6x = 6*25 = 150
